1 Answers
China VI emission standards are 40%-50% stricter than China V, making them one of the most stringent emission standards globally. More details about emission standards are as follows: 1. Vehicle Emission Standards: These refer to the regulations on the content of harmful gases emitted from vehicle exhaust, such as carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and soot. Many newly launched vehicles now comply with China VI emission standards. 2. China VI emission standards are implemented in two phases: (1) Phase One: Starting from July 1, 2020, all vehicles sold and registered must comply with China VI-A standards. (2) Phase Two: Starting from July 1, 2023, all vehicles sold and registered must comply with China VI-B standards. Some cities will implement China VI emission standards for light-duty vehicles ahead of schedule, starting from January 1, 2019.
